Have HVAC Questions? Ask an HVAC Expert for Answers
I won't be able to guess the system size without that. I would just charge by superheat or subcooling until proper charge is achieved
Im going to opt out and see if another expert can help
I understand your question but it could be 10lbs or it could be 50lbs I can't tell you exactly with out a model number, my recommendation and what I would do In the field is charge by superheat or subcooling
Previous expert is correct that we would need a model number to look up the factory charge.To ask without the model is like asking what spark plug a 40 year old Chevy would use without knowing what engine was in it.Do you have any info at all that may lead us in the direction to find charge? Is it a single or dual circuit?
As a rule of thumb about 20lbs of refrigerant for each circuit in a 20 ton 2 circuit system would be normal
Here is an example with a single circuit where charge shows 29.6 lbs, So as you can see the model is going to be of utmost importance
So if we use the old standard 20 lbs per 10 ton circuit we would be way overcharged
Will do.My local York Dealer is M&S Supply.I will give him a call tomorrow and see if he can help us
As you can see below there are just a bunch of different York packaged units.(and this is just some of them)Maybe the age will help us narrow it down.Will let you know.
Called York this morning .As far back as they can pull up specs is 1995. Those units total charge was 37.6 lbs
